SPRING SHOE.

'Application med Apri; 16, 1925. serial No. 23,536.

The present jinvention yhas'to ldo withaf'toy or amusement device providing novel en-1 ercise means for thewearer.

- Among the objects ot the invention, are the following :-l

A device or scientiiic vCon's'truction based on principles adapted ftogive' to a wearer the greatest amount ot pleasure wisthalnliiiimum amount of danger;

yA spring shoe comprising a plurality' of y properly proportioned members land. intermediate springs of an improvedldeslgn properly correlating theimpacting face with the foot Supporting memberg'and A novel article oil manufacture comprising an unique arrangement of Supporting and impacting rmembers' of dil'l'erent sizes and 1in-- termediate parallel springs, the novelties of;

l construction bei-ngadapted to lprovidesim- 'plicity of 'inanu'facture, fsturdine'ss in con-r struction, 4and means for scientifically eXercising lthe body muscles while obtaining enjoyable and fascinating amusement.

These, vaus "such other l'objects as may hereinafter'appear, are obtained by the novel construction, combination, and arrangement ot the several elements which constitute the device.

One embodiment of the invention is disclosed in the accompanying drawing, hereby made a part of this specification, and in which Figure 1 is a vertical longitudinal section of one form of spring shoe embodying the` invention Figure 2 1s a top view of such embodiment.

Like reference characters are used to des-v ignate similar parts in the drawing and'in the description which follows The shoes are made in pairs, one for the rightvfoot and another for the lett. Only one shoe 'is illustrated.

The device as illustrated comprises a bottom plate 10 of metal having a plurality of ears stamped therein. At the ends, ears 11 are cut in the material and are adapted to bev bent outwardly, while at the center of plate 10, staggered opposed ears 12 of greater dimension than the end ears 11 are similarly provided. A gripping surface or pad 13 of leather, rubber or other resilient material is secured to the under surface of said plate 10.

Two parallel coil Springs 14 are secured to said bottom plate 10. Middle ears 12 are -single convolution oi. a spring 14.

Two centrallyfsituated and oppositely disadapted yto be articulatedinwardly :over two convolutions 'of both of said springs, whlile the yend ears'llly are bent outwardly'fover a 5 The middle ears 12 are. adapted to extend over conl tinuo'us'portions of convolutions oty opposite springs 14. l

A top plate 15 for the shoe of'greater length than the fbottomplate lis provided. Bottom plate [10 :is of such'vdimension that it merely forms a .base toseatsa-id parallel springs '14 and its endfmargins are flush-with the yperimeter thereof. iThe front' extension yof the rupper or ltop rp'la'te '15.' projects further beyond the front spring 14 fthanthe rearend vprojects beyond the lrear section of rear @spring 14.. Ears; 1G correspondingy to ftheend ears f 11- of--the lower plate 10 are provided .adjacf-)ntl the front and back of the topplate l5fand these are bent'over a s inglefconvolution of springs vposed -eais 17 preferably staggered, L,oi greater dimension than thefront and back ears 16; just mentioned are adapted to be articulated downwardly and about two of the convolutions of each of the springs 14. The material of said ears 17 while notoverlapping actually, extends over adjacent contiguous sections of the convolutions of both of said springs 14.

At the rear of the top plate 15 are three extension portions 18 adapted to be'turned upwardly to provide flanges. To these flanges 18the ankle portion of a strap 19, quite like that used on a roller skate, is secured. A curved gheel plate 2O is formed about the rear or heel of the plate 15, and

' rivets or other suitable fastening means are provided and which extend through said heel plate 20, the leatherof the strap 19, and said upturned flanges v18, thus securing said strap 19 to the device.

A front strap 21 is adapted to be secured to the top plate 15 through slots 22l in said top plate adjacent its edges and near the front thereof and by inserting the strap 21 therethrough.

The present form of invention is a decided improvement in a spring shoe. The lower plate 10 is of less dimension than the to-p plate 15 which has extension portions over the bottom plate 10 proportioned to properly balance the user SO that his Vor her weight is distributed in a. manner suitable for Walking, jumping or running while maintaining a perfectly balanced control.

Arranging the bottom plate l0 so that it corresponds to the periphery or perimeter face, and to avoid any tendency of the footto twist or turn.

I claim 1. A spring shoe con'iprising ripper and. lower plates, means for securing the upper plate to a shoe, and two coil springs secured between the plates by strips of metal partially severed from the plates and forming straps, extending around one convolution of the spring, the straps in the center of the plate extending around a convolution of both springs, said lower plate having .its margins substantially iush with the outside periphery of said springs.

2. A spring shoe comprising superposed plates,` intermediate parallel contiguous springs and means for fastening the uppermost of said plates to thefoot, the uppermost of said plates overlapping the'lowermost at each end, said lowermost plate being of a length substantially identical with the sum of the diameters of said springs.

8. A spring shoe comprising'super-posed plates, intermediate parallel contiguous springs and means for fastening the uppermost of said plates to the foot, the uppermost of said plates overlapping the lowermost at each end, said plates being formed from blanks of the same width, the end marginsof the lower `blanl; being flush with the periphery of said springs, and the upper plate extending over the lower plate a greater distance at the front than at the rear. 4. A spring shoe comprising superposed plates intermediate contiguous springs, antV means for fastening the uppermost of said plates to the foot, the uppermost of said plates overlapping the lowermost plate :at each end, said lowermost plate being of a length substantially identical with the sum of the diameter of said springs. y'

5. A spring shoe comprising supcrposed plates, intermediate contiguous springs, and means for fastening the uppermost of said plates to the foot, the `uppermost of said plates overlapping the lowermost plate at each end, the end margins of the lower 'plate being flush with the periphery of said springs, and the upper plate extending over the lower plate a. greater distance at the front than at the rear.
